LOOK at the examples given. => There is one example exactly for that.

All of the examples of Eva in this thread appear to be "subdivided" since I can detect polygon edges that are wavy between their points. This doesn't happen with real polygons.

Poser can do the very - exact - same thing if you want it to.
But it does not do it in preview; Poser does it at render time.

Not exactly. Poser has a form of smoothing, but one of the reasons given for Poser's inability to serve as a platform for Genesis is that it lacks the ubiquitous Catmull–Clark subdivision method and consequently doesn't bend the figures as nicely.
